Amphiscirpus was segregated from Scirpus (A. A. Oteng-Yeboah 1974) mainly on the basis of the culm anatomy, including the absence of internal air cavities. It differs from all species of Schoenoplectus in its prominently ciliate ligules. Amphiscirpus was treated within the high Andean Phylloscirpus (J. J. Bruhl 1995) and also as a distinct, monotypic genus (P. Goetghebeur and D. A. Simpson 1991).
